<P>PROBLEM TO BE SOLVED: To provide a liquid discharger which is suitable when using a liquid against contact with the outside air, reliably shuts off the contact with the outside air during the storage, and sufficiently maintains a quality even after starting the use, and is convenient in handling. <P>SOLUTION: The liquid discharger has a flexible barrel portion 2, a container body "A" in which an opening of a neck portion 4 is closed by a pressure-breakable lid plate 5, is formed of an oxygen non-permeable synthetic resin, and the lid plate is formed of an oxygen non-permeable material. A connection pipe 35 to communicate with a cylinder 31 is vertically suspended from a lower end of a pump C, a fitting cap 30 is screwed to the outer circumference of the neck portion 4 in a state before the connection pipe 35 cuts off the lid plate 5, the fitting cap is screwed down when being unsealed to pressure-break the lid plate 5 by the connection pipe so that the container body "A" communicates with the cylinder 31. <P>COPYRIGHT: (C)2007,JPO&INPIT |
